To- 1.1.1. whom it may concern: I

Be it known that I, HENRY P. CLAUSEN, a citizen of the United States of America, and I a resident of Chicago, Cook county,.lllinois, have invented certain new and useful. lmprovcinents in Self-Restoring Signaling Del vices, of which the following is a specification. I

My invention relates to self'restoring sigl na'l devices, I and has special reference to l those. used in connection with telephone centralmfiice apparatus.

It has for its primary object the siniplification of instruments of the class described, whereby they will consist of butfew parts, be e'l'licient in operation, and cheap to construct.

it therefore consists in a signaling. device, l such as s relay, having a main coil, preferably inclosed in a tubular shell, and a restoring coil in line with the main coil and also suit ably inclosed, the said coils being preferably secured to opposite faces of a supportingplate. Ali-armature for the main coil is provided and also one for the restoring-coil, and an arm or lever rigidly secured to the latter armature andv extends longitudinally of the coils to the ot er end of the relay, where its free end normally rests upon the other armature. An electrical contact is curries by the restoring-coil armature to close a. local circuit containing the signal-indicating device.- lvleans are also provided for preventing the main-coil armatureiroin freezing to the poles of the magnet.

The invention also consists in the novel de tails of construction and combinations oi parts hereinafter fully described, and particularly set forth in the appended claims, reierence being; had to the accompan ing drawings, forming a part hereof, in whic the same reference characters designate like parts throughout the several views, and in Which- Figure l is a side elevation of the relay, Fig. 2, a plan view of the same Fig. 3, s. longitudinul sectional elevation thereof; Figs. 4 and 5, elevational views of the main-coil and restoring-coil ends of the-magnet, respectively. Fig. 6 is an enlarged sectional detail view showing the operation of the armatures and contacts.

Fig 7 is a pers ective of the arm 01' lever and the armature 'or the restor- Fig. 8 is a perspective of the armaturefor the resin or signaling coil. FigsQ and 10 are diagrammatic views illustrating two different applications of my 'll'lVGIltlOll.

in the fi ures, 2 and 3 denote, respectively, the main and restoring magnets provided with the tubular shells t andv 5 and inclosed end pieces 6 and 7, which serve to complete tie magnet-circuits those ends of the msgnets from the shells 4. and 5 to the cores 8 and 9 of the two magnets, the latter being secured to the end pieces 6 and 7 by the screws 6' and 7*, and which plates 6 and 7 are secured to the main supporting-plate 1.0 on opposite sides thereof through the medium of cars or lugs 11 on said shells, through which screws are adapted to be inserted and threaded into the said end pieces 6 and 7. This plate is preferably the main supporting-plate of the relay and can be secured in any c esircd mannor to the said support. If it be considered desirableto installs bank of such relays, the said plate may be extended and a plurality of coils attached thereto. As shown, these coils are placed with their inclosed or rear ends on opposite sides of the supportingplate 10 and. in line with each other, an aperture ii in the plate 10 being provided above the said magnets and the plates 6 and 7 suit ably notched, lor purpose hereinafter explained.

The main-coil shell 4 at its forward end. has secured thereto a castin r 12, as by screws 13, in the projecting ears or ugs 12 of which the armature M is pivoted upon the pivot-screws 15, passing throughsaid ears. This armature 14.- is circular except at its lower portion, where it is provided with a squared section 14 containing the pivot-pin sockets i l This armature 14, as well as the insulatingdisk-l5*, interposed between the core 8 and. the shell t to properly support and s ace them apart, have apertures through Whic themagnet-coil terminals 16 extend and to which thc external circuit-wires may be connected, the a ertures 14 throu h the armature 14 being or such size es to a low a slight vibration of the armature without "touching said terminals. Any other. suitable or n'e'ferred con struction and arrangement of t iese terminals may beadopted; but that shown is deemed best. v

, At the other end of the relay-or at the for ward or open end of the restoring-coil shell 5 and on its upper side a small brass ca ing IOO ,upon the armature, a small pl 17, similar to the casting 12, is secured by the screws 18 and is also provided with cars 19, projecting beyond the end of the shell 5, in which. the restoring-coil armature 130 is pivoted upon the pivot-screws .21, so as to vihrate Freely. This armature is also circular, except at the upper portion o1" its edge, which car 'ies a rectangular portion for the pivotsoclaets, this portion being provided with an extension 22, Fig. 7, on. its upper edge, to the re; 1 or inner side of which the catch-lever or arin 2? is rigidly secured in any desired manner and extends through the aperture .1]. in the plate to the other end oi the relay, where it is provided with a downwardly-ex.- tending end lug or catch 24, projecting over and beyond the outer and upper edge of the armature l4 and having the lower edge 24 ol the catch 24 normally resting upon a small lug 25, carried by the armature 14 on its outer face and near the upper edge of the sam e it being riveted in an aperture therein, as shown in Fig. 6, or secured thereto by any preferred construction.

The armature has holes 20? therethrough large enough to avoid touching the inagnetterminals 5, which are secured in the insulating-bushing 5 and to which the magneh Wires are soldered, all in the usual w. This arrangement and. construction is such that when the main coil is energized and its armature 14 attracted the lug carried by the lever ilij, slips oil the lug on the armature 14, as shown in Fig. 6, and'allows this end oi the lever to drop by gravity and moving the armature away from its nmgnchpoles.

When the restoring-coil is energized, the armature 20 is attracted to its normal position and lifts the. arm 23, allowing ti 2 armature l-l to fall or drop hack liy gravity with the said lug or rest 25 liei'ieatli the catch 24 of the seid arm.

in order to he sure that the :1 rn mture will fall halal: away from the end of the shell 4 and not stick or freeze thereto wlr the lever is lilted without the use of spi Jigs acting cured to said armature in an and preferably lwneuth the lug so so as to project horiiontally or at ri ht angles therefrom. A slot 27 is providcilnear the outer edge of said proit ting plate, through which a light spring 25%, secured to the end ol tlienrni 23, is adapted to pass. is shown in. Fig. thcslot 27 is of such width and the spring is so adjusted that when the arinaiiire is at tracted the spring and slot present uo ohstacle to the nioveinei'it of the :u'niature, and thereby alloi' the end 24 o! lever LI'J to fall until its lower edge E l strikes upon the plate 25, (see dotted lines;) but when the arm 23 is lifted, as. in the operation of coil 3, the sprin iilhears against the outer edge of the slot :27

The a} )pe. ratus for accoinplislun this purpose consists in-a spring 80, rigidly attached at its upper end, as by rivetirg, to the projection 22 of. the tll'lniltlli) 5.20, its lower erd being raised slightly above the. face of the armature and adapted to contact with the pointed end of the stationary screw-cxmtact 31., insulatingly supported by washer f3 driven into an aperture in the narrow vertiml brass plate or tongue 33, supported oeyond the end of the restoringanagtet through the medium of integral 3 1%, extcndiiu horizontally at right angles to the plate 33 on each side of the projection 22 of the armature 20 and secured by screws to the said cc, ting 1.7.

coil oi the clearing-out i ingszoil 5" is in a lcal circuit contiziningthe battery 45, ceniiluetors i6 and 47, and the l-:ey.sWitch terminals 4&1 :which are adapted to he closed. upon the actuation of the listennw-ltey 4L9 tov connect the operators telelamp n. n

phone 49' with the cord-circuit. A parallel branch is taken oil from each side of the battery 45 and contains the relay-contacts 30 and Eli and the supervisory or clearing-out hen the cord-circuit is in use and the subscribers ring oil, the coil '2 will be actuated and the lever 23 dropped to close at the armature through contacts and 31, the local circuit containing the lamp 442 and battery at which causes the lamp to g've a signal. The operator upon seeing this signal will connect her telephone e9 by means of the listening-key 49 with the cord-circuit to ascertain the meaning of the signal before withdrawing the plug, which act closes the circuit from the same battery through the restoring-magnet 3 and restores the relay and signal to normal condition, the spring 28 serving to push armature 14 away from the poles of its magnet.

in Fig. 10 another use of the relay isindi catcd. designates a telephone-line terminating at the spring-jacl 51 and having bridged thereacross the main coil 2 of the relay. T he restoring-coil is in a local circuit, as before, containing the battery 56 and tcrminals 57 oi the jack, a parallel branch to the battery including the lamp and relay-contacts 3i) and 3]. Upon sending in a signal the coil 2 is actuated to close the local circuit c'oiuyaining the lamp 55 and battery 56, which. signal remains exposed due to the weight of the arm until the plug 58,in

answer to the signal, is inserted in the jack 51 andtne local circuit containing the restoring'coil and battery 56 is completed to restore arnrilg and extinguish the signal 55. Thus it will be seen that the coil 2 and armature 14 respond to a signaling-current and that the coil 3 and armature 2O respond to a restoring-current. it will also be seen that the arm or lever 23 serves as a weight or weighted cciinection for closing a current through signaling device. It will also ,be seen that the mainor signaling armaturel l serves as a means i'or releasing this Weight or weighted connection upon the energization of the signaling-coil. in this way the said main or signaling armature 1e permits the weight or weighted connection represented by the arm or lever 23 to fall, and thereby close the contacts 30 and 31. The energization oi the coil 3 causes the restoring armature 20 to lift the weight 23 and also causes the said contacts to separate,so as to extinguish or restore the signal. The ener gization of the coil 3 and the consequent 'movement of the restoring-armature20 and the Weight or lever 28 operate to positively move the signaling-armature 14 a short distance away from the ma net of the signalingcoil 2, and after being thus started the said armature 14 then falls or moves outward by gravity to the full limit of its movement. As

previously explained, this outward swing on the part of the armature 14 operates to bring the shoulder 25 below the nose or heel of the weighted arm 23, and in this way the restoring-coil and armature also serve to 0perate the locking device adapted and arranged to lock the arm or weighted connec tion in its normal or elevated position and also to lock the contacts 30 and 31 apart. In this way both armatures may be regarded as having a double function, the signaling-an mature 14 serving both as a means for operating the devices which close the local Cir,

cuit and also a means for locking such circuit-closing devices in an open or unclosed condition. The armature 20, as shown and arranged, serves both as a means for enabling the weight 23 to bring the contact 30 into engagement with the contact 31 and also as a means for separating thesecontacts and for operating the locking device which locks the contacts apart.

I wish it understood that the invention is not limited to the precise details shown, for I hold it to include such changes and modifications as fairly fall within the scope and spirit thereof.
